Red Hat Security Advisory

 

Synopsis: Important: bind security update

Advisory ID: RHSA-2012:1365-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1365.html

Issue date: 2012-10-12

CVE Names: CVE-2012-4244 CVE-2012-5166

=====================================================================

 

1. Summary:

 

Updated bind packages that fix two security issues are now available for

Red Hat Enterprise Linux 4 Extended Life Cycle Support.

 

The Red Hat Security Response Team has rated this update as having

important security impact. Common Vulnerability Scoring System (CVSS) base

scores, which give detailed severity ratings, are available for each

vulnerability from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux AS (v. 4 ELS) - i386, ia64, x86_64

Red Hat Enterprise Linux ES (v. 4 ELS) - i386, x86_64

 

3. Description:

 

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain

Name System (DNS) protocols. BIND includes a DNS server (named); a resolver

library (routines for applications to use when interfacing with DNS); and

tools for verifying that the DNS server is operating correctly.

 

A flaw was found in the way BIND handled resource records with a large

RDATA value. A malicious owner of a DNS domain could use this flaw to

create specially-crafted DNS resource records, that would cause a recursive

resolver or secondary server to exit unexpectedly with an assertion

failure. (CVE-2012-4244)

 

A flaw was found in the way BIND handled certain combinations of resource

records. A remote attacker could use this flaw to cause a recursive

resolver, or an authoritative server in certain configurations, to lockup.

(CVE-2012-5166)

 

Users of bind are advised to upgrade to these updated packages, which

correct these issues. After installing the update, the BIND daemon (named)

will be restarted automatically.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to
